RE: Addressing Orchestration

David,
When you use the term choreography/orchestration, do 
you refer to public interfaces (aka Business Partner 
Protocols) such as RosettaNet PIPs, BPSS, WSCI or 
private implementations BPML, XPDL?

Do you see the need for asynchrony (message 
correlation and callback pattern) as included in the 
choreography requirements or as something that could 
be adopted as a smaller step and then leveraged by 
the choreography?

Thank you,

Edwin
